Analysis: Solar energy writer John Perlin argues that Solyndra's fall from grace reflects a bad choice in technique, and not a fundamental problem with solar energy.

Some environmental advocates say the federal government is ignoring the real future of solar energy: photovoltaic cells on almost every roof. But even supporters acknowledge rooftop solar isn't the complete answer to the energy question — yet.

Big money, big energy and big environmentalism join forces to support big solar energy projects on federal land in the Southwest. But could these "green" projects actually be anti-environmental boondoggles in the making?
